How did galileo confirm copernicus's theories on the universe?

galileo was able break copernicus's ideas down into smaller, simpler parts.
galileo was able to use advanced calculus to prove copernicus's ideas true.
galileo was able to use newton's ideas on gravity to prove copernicus correct.
galileo was able to observe that not every moving body circled the earth.

Galileo was able to observe that not every moving body circled the Earth

Explanation:

Galileo noticed with the help of a telescope (which was invented earlier) that the moons of the Jupiter were orbiting Jupiter. By this analogy, he concluded that the planets orbit the sun, which is not a relevant scientific proof but a hypothesis.

He faced the problem because he could not perceive that the planets were orbiting the sun similarly. So this part of the theory could not be proved in any way.
